- 讨论了一般符号模式矩阵的幂等性和广义逆。
I discuss idempotent, generalized inverses of general sign pattern matrix. - 通过幂等的定义,给出了两种符号幂等模式矩阵的结构。
Meanwhile, we give two structures of the sign idempotent by the definition of idempotent. - 本文主要研究了符号幂等矩阵和对称符号模式矩阵的性质及它们之间的关系,特别是符号幂等矩阵的负元素的个数。
In this paper, we mainly study the sign idempotent of sign patterns, symmetric sign patterns and their relations, especially the number of negative entries that occur in sign idempotent sign pattern.
